Neutropenia (Low White Blood Count)

Neutropenia (Low White Blood Count)
Your blood is made up of many solid particles, cells and fluid. One type of cell is your white blood cells.
Neutrophils (new-tro-phil-s) are a specific type of white blood cell.
White blood cells fight infection and neutrophils start the fight.
Neutropenia (new-tro-pee-ne-a) happens when you do not have enough neutrophils. If you have this
problem you are neutropenic. You are at a greater risk of infection when you do not have enough
neutrophils.
The lower your white blood cell count (WBC) the higher your risk of infection. It is very important that
infections are caught early and treated quickly.
A normal white blood cell count is between 4,500 -11,000 (or 4.5-11). Your white blood cell count may go
as low as 100 (or .1).
Absolute Neutrophil Count (ANC) is the term used to describe the number of neutrophils in your blood.
A normal ANC is about 2500-7500 (or 2.5-7.5).
What causes neutropenia?
Neutrophils, like other blood cells, are made in your bone marrow and released into the blood stream.
Some cancer treatments, certain types of cancer and other illnesses can affect the bone marrow so not
enough neutrophils are made.
Stem Cell Transplant and cancer systemic therapy (sometimes called chemo) may lower your white
blood cell count temporarily. Usually, your blood counts will be at their lowest 10-14 days after cancer
treatment. Usually, your counts will return to normal over the next 2 weeks. Your blood counts will be
checked before each treatment.
Your doctor, nurse, or pharmacist can tell you how much of a problem neutropenia is with your type of
cancer and your treatment.
When would my doctor prescribe medication to prevent neutropenia?
Your doctor may prescribe a growth factor to prevent neutropenia. Growth factors like GCSF®,
Neupogen®, or Neulasta® are used to reduce the risk of neutropenia. Growth factors cause the bone
marrow to release neutrophils into the blood.
Growth factors are prescribed in the following situations:
• T he chemotherapy you are having is known to cause neutropenia more than 20% of the time
• Y ou have previously developed febrile neutropenia after chemotherapy
• Y ou have had a delay in your chemotherapy because of neutropenia
What are the signs and symptoms of an infection?
Often the only sign of an infection is an increase in your temperature. Make sure you have a digital oral
thermometer at home, that you are able to easily read.
Take your temperature when you feel warm, chilled or unwell. Your doctor or nurse may ask you to take
your temperature more often.
Unless directed by your doctor or nurse, do not take acetaminophen (Tylenol®), ibuprofen (Advil®,
Motrin®) or naproxen(Aleve®). These drugs can prevent a fever from being noticed. Please talk to your
doctor or nurse if you need pain medication.
An infection can occur anywhere. Most infections occur in the mouth, blood, lungs, bladder, kidneys and
skin.
It is very important that infections are caught early and treated quickly. If you have any of the following
symptoms, call your nurse or doctor, right away:
• A new sore mouth or throat
• Pain or difficulty passing urine
• New diarrhea
• Swelling, redness, rash, or drainage on your skin
• New cough or shortness of breath
• “Flu-like” feelings
Contact your doctor or nurse with any other questions or concerns.
What is the Fever Card?
You will get a yellow card that tells you and the Emergency Department Staff what to do if you have a
fever.
The yellow card alerts Emergency Department staff that you are a Cancer, Hematology or Stem Cell
Transplant Patient with a fever, who should be treated within 60 minutes.
Although your care is a priority, you may still have to wait while other patients, with more urgent
concerns, are treated.
You should only use the yellow card if you have a fever. If you need to go to the Emergency Department
for another reason, you do not need to show your yellow card; just tell the staff you are a cancer patient
and give them a list of your medications.
When should I go to the Emergency Department?
It is very important that infections are caught early and treated quickly.
If you have a temperature of 38°C (100°F) or higher, or uncontrolled shivering go to your nearest
Emergency Department right away.
Give the Emergency Department staff your yellow card, a list of your medications and tell them the date
and type of your last cancer treatment.
In the Emergency Department, you do not need to be kept away from other patients.

Call your doctor or nurse if the wound does not heal or becomes red, swollen, sore or has drainage.
